Michael F. Aylward

Michael is a partner in the Boston office of Morrison Mahoney, where he chairs the firm's complex insurance claims resolution group.  For the past four decades, he has represented insurers and reinsurers in disputes around the country concerning the application of liability insurance policies to commercial claims involving intellectual property disputes, environmental and mass tort claims and construction defect litigation as well as bad faith claims arising out of such disputes. Michael has also served as an AAA-certified arbitrator in numerous insurance coverage matters and has testified as an expert in matters involving coverage and reinsurance issues arising out of such claims. He has taken a leading role in the major defense bar associations, including DRI, FDCC and IADC and is the President-Elect of the American College of Coverage and Extra-Contractual Counsel.

Michael has delivered over a hundred papers over the past four decades on issues relating to insurance coverage, bad faith, emerging liability topics and, most recently, cognitive issues involving the reading of digital briefs by appellate judges; cyber-threats to the U.S. energy grid and the potential impact of the American Law Institute’s Restatement of Law, Liability Insurance on the scope and prosecution of bad faith claims in the United States.
